CUFF=BUTTON.

SPECIFICATION forming part of Letters Patent No 322,208, dated July 14, 1885.

Application filed April 30, 18%. (No model.)

ToaZZ whom it"may concern.-

Be it known that I, ELIAS M. STEWART, of Richmond, Canada, have invented a new and Improved Cuff-Button, of which the following is a full, clear, and exact description.

This invention relates to certain new and useful improvements in that class of cuffbuttons in which the base is formed of two pieces, one of which can be locked across the to other to prevent withdrawing the button.

The invention consists in the combination, with a hollow head having a tubular shank provided with a cross piece, of a pin arranged to turn in the shank, a cross-piece on the pin, a sliding rod passed through the upper end of the pin, and a head on the outer end of the rod, which head has a rib forlocking the rod in place.

Reference is to be had to the accompanying 2o drawings,forming apart of this specification,in

which similar letters of reference indicate corresponding parts in all the figures.

Figure l is aside View of my improved cud-button. Fig. 2 is a sectional plan view of the same on the line m m, Fig. 1. Fig. 3 is a plan view of the bottom of the button, the two cross-pieces being folded. Fig, 4 is a similar view, the cross-pieces being crossed.

Fig. 5 is a cross-sectional view of the same on 0 the line as 00, Fig. 2.

The hollow head A, in which the top plate, gem, or stone, B, is held, is pivoted with the hollow shank or stem 0, on the lower end of which the cross-piece D is held, which has a central aperture coinciding with the bore of the shank G. A pin,E, is arranged to turn in the hollow shank G,and on the lower end of the same a cross-piece, F, of the same size and shape as the crosspiece D, is secured below 0 the said cross-piece D. Arod, G, is passed through the upper end of the .pin E,within the head, and is arranged to slide in the said pin. On the outer end of the rod G a sliding head, J, is arranged, which projects through 4 5 a segmental slot, K, in the rim of the head A, and preferably has its outer edge serrated. A longitudinal rib, L, is formed on the head J, and is adapted to pass into notches M at the ends of the slot K. A spiral spring, 0, surrounds the rod G, between the pin E, and the head .I, and presses the latter outward, the out= ward movement of the rod being limited by a shoulder, L, of the rib L.

The operation is as follows: When the cross-pieces F and'D cover each other, the rib L is in one end notch M. The crosspieces F and D are then passed through the button-hole, and the head J pushed inward to move the rib L out of the notch M. The head J is then moved to the other end of the slot 6 K, where the head J is pushed outward by the spring, and the rib L passed into the other notch M, and thus locking the rod G, the pin E, and the cross-piece F in place, the. said cross-piece F extending across the crosspiece D, as shown in Fig. 4, and preventing wiizhdrawing of the button from the buttonho e.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 7c 1. In a cuff-button, the combination, with a hollow head and hollow shank having a cross-piece on its lower end, of a pin fitted to turn in the button-shank and a cross-piece on the lower end of the pin, a sliding rod 7 held in the upper end of the pin, and a sliding head on the rod projecting through a slot in the head, substantially as herein shown and described.

2. In a cuff-button, the combination, with 8 the hollow head A and button-shank O,having a cross-piece, D, of the pin E in the shank, the cross-piece F on the lower end of the same, the sliding rod G in the top of the pin E, thesliding head on the rod G, project- 8 ing through a'slot in the side of the button, and of a spring for pressing the head outward, substantially as herein shown and described. I

3. In a cuff-button, the combination, with, the head A, having the slot K and notches M 9( in its side, of the tubular shank G, the cross piece D,the pin-E,the cross-piece F, the sliding I rod G on the top of the pin E, the sliding" head J, having a rib L, and of the spring 0, substantially as herein shown and described.
